Duluth police say their raid at The Last Place on Earth netted 20,000 packs of what they suspect is synthetic marijuana. Meanwhile, authorities were also seizing $2.8 million from the bank accounts of the shop's owner, Jim Carlson. The raid was part of a national crackdown on suspected sellers of synthetic drugs.

Past laws banning specific compounds have simply prompted chemists to create new "analogs" -- similar compounds with the same effects -- to get around the rules. New legislation at the Capitol has broader language that sponsors say would ban both existing synthetics and their analogs.

An attorney for St. Louis County tells the Duluth News Tribune he expects to file charges against the Last Place on Earth. Police raided the shop in September and reportedly took synthetic marijuana, cash and 31 guns. The shop claims that was illegal search and seizure.

WCCO reports the Justice Department has indicted two dozen people with alleged connections to a crime ring known as the "Native Mob." Authorities believe the gang has about 200 members and connections to communities in Minnesota. Police reportedly conducted raids on the White Earth, Mille Lacs, and Leech Lake Indian reservations, as well as in the Twin Cities.
